Snoring is usually harmless (with the exception of possibly strained relationships.) However, for some people, snoring is an indication that a more serious condition is present – sleep apnea. Sleep apnea involves the repetitive blockage during sleep of the airway we use to breath. This can cause a sleep apnea sufferer to wake from deep sleep many times a night, a fact the individual is usually not aware of. Sleep apnea has wide-ranging health effects. Thankfully, oral appliances can successfully open the airway and relieve the symptoms of sleep apnea. Many who snore (but don't have sleep apnea) also choose to seek treatment in order to help their sleeping partner rest more peacefully.
